The author's attitude towards Carl Menger is that of:Elation.Exultation.Adulation.Admiration.

To analyze the author's attitude towards Carl Menger, we should consider the meanings of each option:

1. Elation - A feeling of great joy or pride.
2. Exultation - A feeling of triumphant happiness or joy.
3. Adulation - Excessive admiration or praise.
4. Admiration - Respect and warm approval.

When evaluating these options, the goal is to determine which word best captures the tone and sentiment the author expresses regarding Carl Menger.

The context in which Carl Menger is discussed is crucial. If the author's writing conveys deep respect and reverence for Menger’s contributions to economics, “adulation” or “admiration” would be the strongest contenders. If the discussion is more about emotional uplift or joy regarding Menger's impact, then “elation” or “exultation” could be fitting.

In most academic discussions focused on historical figures or theorists, "admiration" tends to best represent a respectful and professional appreciation. Therefore, without additional context, the most appropriate answer would likely be “Admiration.”

Final Answer

Admiration.
